I have the XIED's from new on a stock 08CVO. I had the bike dynoed just to see how it looked. WOT runs were OK with 81 Hp and 125Nm. AFR at around 14. Testing with load at partial throttle (equivalent on the dyno of 12 through 150 km/h) yielded an AFR of 13,8, precisely as Nightrider promised. Exhausts are still looking very clean after 1.500 km. In American Iron magazine from april they tested an S&S Quick setup kit (AC and exhaust) without any recalibration or tuner. They stated that after 15 minutes of operation the ECM adapted so much that the engine looked well on the dyno. From the dyno sheets you could also see that the AC increased te power but the slip-ons did not do anything. I still have the stock exhaust and will keep it that way. There is nothing more pathetic than lots of noise without a real increase in power, I might as well go around blowing the horn the whole day. I ordered a SEAC kit and intend to put the bike on the dyno after installing it, to see whether it increases power and make sure it does not run to lean at cruising speeds. This will happen after my holidays but I wll keep you posted. The more I read about tuning systems and especially tuners on these forums the less I am inclined to believe that they know what they are talking about. I am no expert myself, but I have enough common sense and experience to see when people are BS'ing. For example I have to see the first post of a tuner that effectively uses the ION-sensing system in the Delphi ECM when tuning with SERT or SEST. This is a highly sophisticated system to keep the engine running just shy of detonation and therefore increases the effiency of the engine. When you do not use systems like these that are in the standard Delphi ECM you are just not using the system to its full potential. And I think it is because they are in it over their heads. Sure they will be able to extract more power from a bike after investing a lot of money, but is it better. I think they just make different choices with regard to reliabilty, drivability, emissions etc. With the XIED's you adress the issue of emission/heat in closed loop mode, with the SEAC you can add perhaps 10-15 Hp (remains to be seen) and a very drivable bike, I will settle for that.
